[0034] Example:
[0035] like Figure 1 As shown, this utility model discloses a hot air knife desoldering device, including a main body base 1, a hot melt impurity removal box 2, and a processing and transfer mechanism. The main components of this utility model will be described in detail below:
[0036] like Figure 1 and Figure 2 As shown, the top of the main body base 1 is provided with two air nozzles 11, and the lower end of the air nozzles 11 is connected to the compressed air intake pipe 13 through the heating module 12.
[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the hot melt impurity removal box 2 is detachably installed on the top of the main body base 1. The bottom of the hot melt impurity removal box 2 is provided with an avoidance hole 21 corresponding to the air nozzle 11, and the top of the hot melt impurity removal box 2 is provided with a processing channel 22.
[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the processing and transfer mechanism is located outside the hot melt impurity removal box 2. The moving end of the processing and transfer mechanism is equipped with a rotatable material picking and placing head. The material picking and placing head can pass through the processing channel 22 to reach the air outlet of the air nozzle 11.
[0039] refer to Figure 1 , Figure 2 and Figure 3 As shown, the usage method and principle of this utility model are as follows: Open the valve of the compressed air inlet pipe 13 to ensure that the airflow enters the heating module 12 stably, turn on the power of the heating module 12, set the required heating temperature, and let the device run for a period of time to ensure that the nozzle 11 can spray out a uniform high-temperature airflow; start the processing transfer mechanism and grab the material to be processed through the material pick-and-place working head; the material pick-and-place working head moves the material to be processed to the air outlet of the nozzle 11 through the processing channel 22, and the high-temperature airflow heats the surface of the material, so that impurities (such as residual solder paste, plastic burrs, glue residue, etc.) are melted or softened by the heat, and then peeled off from the surface of the material by the airflow; it should be noted that during this process, the material pick-and-place working head can also drive the material to rotate at high speed, and use centrifugal force to throw out the melted impurities, thereby improving the cleaning effect of the material; after processing is completed, the processing transfer mechanism moves the material pick-and-place working head out of the hot melt impurity removal box 2, takes out the processed material, and then repeats the above steps to clean the next material. When the cleaning operation is completed or there are too many impurities remaining in the hot melt impurity removal box 2, turn off the power to the heating module 12 to stop heating, close the valve of the compressed air intake pipe 13 to stop the airflow supply, disassemble the hot melt impurity removal box 2, clean the residue in the air nozzle 11, the clearance hole 21 and the processing channel 22, and keep the device clean.
[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the hot melt impurity removal box 2 is a sloping structure. The air outlet of the air nozzle 11 is set facing the upper end of the sloping structure, which makes it easy to adjust the working angle of the material handling head so that the air outlet of the air nozzle 11 faces the inside of the hot melt impurity removal box 2, and avoids the high temperature airflow formed at the air nozzle 11 blowing impurities on electronic components or solder pads to the outside of the hot melt impurity removal box.
[0041] like Figure 1 and Figure 2 As shown, the nozzle 11 is rotatably connected to the top of the main body base 1, ensuring that the hot air is precisely applied to the material surface and improving operational flexibility.
[0042] like Figure 1 , Figure 2 and Figure 3As shown, the bottom of the hot melt impurity removal box 2 is provided with a mounting hole 23. The mounting hole 23 is provided with a connected clearance clamp 23a and a snap clamp 23b. The top of the main body base 1 is provided with a limiting screw 14 corresponding to the mounting hole 23. The diameter of the nut of the limiting screw 14 is larger than the opening size of the snap clamp 23b and smaller than the opening size of the clearance clamp 23a. The diameter of the screw of the limiting screw 14 is smaller than the opening size of the snap clamp 23b, which facilitates disassembly and maintenance.
[0043] like Figure 1 and Figure 2 As shown, the heating module 12 has a heating chamber, in which a heating core is arranged. The nozzle 11 and the compressed air intake pipe 13 are connected through the heating chamber to ensure that the compressed air is fully heated and the airflow is stable.
[0044] like Figure 1 and Figure 2 As shown, the compressed air intake pipe 13 is equipped with a regulating valve, which can precisely control the airflow intensity and is suitable for processing different materials.
[0045] This utility model discloses a hot air knife desoldering device, which achieves efficient, precise, and uniform impurity removal through high-temperature airflow and automated processing technology. Its structure is rationally designed, flexible in operation, and widely applicable. It also boasts advantages such as energy saving, environmental friendliness, and ease of maintenance, making it suitable for impurity removal and cleaning operations in various industrial fields.
[0046] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
